The Spire of Notre-Dame de Paris is located above the cross-section of the cathedral's Transept. Notre-Dame de Paris has had three timber spires made of oak, known as flèches. The first was built between 1220 and 1230. It eventually became so damaged that it was removed in the late 18th century. The second was put into place by the French architect Eugène Viollet-le-Duc in 1859, and destroyed in a major fire on 15 April 2019. Work to construct a third one started in 2022, and was completed when the new copper rooster wind vane was placed on top of the new spire on 16 December 2023, and the third spire was unveiled on 13 February 2024.

A spire is a tall, slender, pointed structure on top of a roof of a building or tower, especially at the summit of church steeples. A spire may have a square, circular, or polygonal plan, with a roughly conical or pyramidal shape. Spires are typically made of stonework or brickwork, or else of timber structures with metal cladding, ceramic tiling, roof shingles, or slates on the exterior.
